+# Dotfiles
+
+These are my dotfiles. As you will notice, they are quite simple. Over the
+years, I have built up many complex and fancy init scripts for many different
+programs, but I've come to realize that sometimes simplicity and defaults are
+better.
+
+The dotfiles here are just the basics—useful aliases and functions that
+have stuck around throughout the years. They're minimal, but useful. The main
+part of my `.ashrc` is the customized prompt, which supports showing the current
+`git` branch.
+
+My shell init scripts are written in POSIX shell, so they should work on any
+shell. As I've hopped from Ubuntu to Arch to OpenBSD to FreeBSD and now to
+Alpine, I've used a lot of shells, and I want my init scripst to work on all
+of them out of the box.
